How Droxia Works
Droxia belongs to a class of drugs known as antimetabolites. It interferes with the growth and reproduction of rapidly dividing cells, such as cancer cells and sickle-shaped red blood cells. In sickle cell anemia, Droxia increases the production of fetal hemoglobin, which helps prevent red blood cells from becoming sickle-shaped and causing complications.
Administration and Dosage
* Oral Administration⁚ Droxia is typically taken orally as capsules, once daily.
* Dosage⁚ The dosage varies depending on the condition being treated, the patient’s weight, and their response to the medication. It’s crucial to follow the doctor’s instructions carefully.
